Deuteronomy 28:23

And thy heaven that is over thy head shall be brass, and the earth that is under thee shall be iron.

The brass heaven and iron earth mean drought and barrenness, with rain withheld from above and no yield from the ground below. It stands among the curses that come upon disobedience to God's commandments, set against the rain, abundance and prosperity promised for obedience, leaving blessing or curse to be chosen. Prosperity or adversity is sent according as His law is obeyed or transgressed, for transgression removes His protection and exposes transgressors to disease, barrenness and their enemies. As transgression grows almost universal the curse is permitted to grow as broad and deep, coming upon land, people, cattle, beasts and vegetation until little remains safe to use. The same image expresses deep spiritual distress and despair, when the future beyond death looks dark with no assurance of happiness and with only fear of accountability.

Words and Covenant Setting

The brass heaven and iron earth mean drought and barrenness under disobedience, in contrast to the rain and abundance promised on condition of obedience. The heavens withhold rain and become like brass, and the earth does not yield its produce and becomes unproductive. Disobedience brings this curse on the land, and the curse grows heavier as disobedience continues, affecting people, animals, trees and vegetation.

The verse belongs with Deuteronomy 26 and 27 as a plain statement of the blessings of obedience. It was read aloud by Moses from the book he had written to all Israel assembled before him, declaring what would come upon them if disobedient, set alongside the promises of God to them if obedient. Its words are not the voice of man but the voice of Christ from the enfolding pillar of cloud. They express the principles of the law of the kingdom of God, made specific and stated plainly for the people's good, so that minds are not left in ignorance and uncertainty. They lay a never-ceasing obligation on all whom God has blessed with life and health and temporal and spiritual advantages, and God's claims in them are just as binding now, just as fresh in importance, as God's gifts are fresh and continual.

In Ahab's time the heavens had become as brass by the word of God, bringing heavy judgments upon Israel. This was God's word bringing covenant judgment and drought on the land, withholding rain. Ahab knew this, yet blamed Elijah for the calamity.

Blessing, Curse, and Obedience

The brass heaven and iron earth belong to the curses that follow disobedience to the commandments, set in direct contrast to the blessings, rain, abundance and prosperity promised on condition of obedience. The promises are conditional, and the chapter places the fearful consequences of transgression against the blessings of obedience so that people must choose whether to suffer disobedience or enjoy obedience. Disobedience brings drought and barrenness as judgment, with rain failing and the land not yielding its produce, while obedience brings promised rain and abundance.

God sends prosperity or adversity according to whether His law is obeyed or transgressed. The ark itself is not the source of success, but it holds the law that represents His authority. Transgression removes protection and leaves the people exposed to the consequences of sin, including becoming prey to their enemies. Keeping His voice, doing right in His sight, hearing His commandments and keeping His statutes preserves His people from disease in health and holiness. Transgressing His law breaks down the barriers erected for protection and brings disease of every kind upon human beings because of sin.

Because of departure from the commandments the curse comes upon the earth itself, upon man, upon cattle and beasts, upon fish of the sea and upon all flesh. The curse includes disease in cattle that makes meat eating dangerous, so that disease is contracted by the use of meat and the diseased flesh of dead carcasses sold in marketplaces brings disease among men as the sure result. As transgression becomes almost universal the curse is permitted to become as broad and as deep as the transgression. The curse on the land grows heavier as people continue in disobedience, with the heavens withholding rain and the earth becoming unproductive, affecting people, animals, trees and vegetation. In a short time nothing coming from animal creation will be safe to use, even the milk of cows will be excluded from the diet, and God's people will be brought into a position where they will not touch nor taste the flesh of dead animals. Those who take God at His word and obey His commandments with a whole heart will be blessed and He will be their shield of protection, but distrust, disobedience and alienation from His will and way place the sinner in a position where the Lord cannot give divine favor.

Image of Spiritual Despair

The brass heavens and iron earth portray a condition of deep spiritual and emotional distress and despair. In that condition the future beyond death appears dark, without hope or assurance. It is a state of spiritual misery with no assurance of happiness beyond the grave, where thoughts of annihilation and of accountability bring fear rather than comfort. In particular it describes Miller's intense despair when he felt cut off from hope, with no assurance of happiness beyond the grave and no relief to be found from fear of death and accountability.
